To all whom it may concern:

Be it known that I, OSCAR HANDLER, a citizen of the Republic of Poland, and re siding at New York, in'the county of New York and State of New York, have invented certain newfand useful Improvements in Machines for the Purpose of Changing the Feet on Watch Dials, ofwhich the following is a specification.

My invention is a machine for the purpose of changing the feet on watch dials, and it consists 1n the combinations, constructions and arrangements herein described and claimed.

An object of the invention is to provide a reliable and efiicient device by the use of which a watch dial can be transferred from one watch to another and accurately positioned on the watch to which it is transferred. a I

A further object of the invention is to provide a deviceof the character described, which 03 112136 used to attain the foregoing object by workmen possessing no unusual Other objects and advantages will be ap parent from the followingdescription, considered in conjunction withythe accompanying drawings, in which: 9

Figure 1 is a front viewof the device embodying'the invention in applied position in respect to a watch dial,

Figure 2 is an edge view of the structure exhibited in Figure 1, c

Flgure 3 1s a rear View of the same structure,

a Figure 4; is a slightly enlarged section substantiallyalong the line 41- 1 of Figure 1, and i I f l a a Figure 5 is a plan view of a tool which is adapted to be used in tightening thereonnections at certain joints of the device;

IFigureQ, and each has the forward end portion thereof reduced in width as indicated at 3 andf, respectively.

The reduced end portions 3 and 4 of. the clamping members are adapted to straddle to the selected a watch dial 6, the reduced portion 3 being disposed at the front of the watch dial.

A pivot element 7 having a tapering end portion adapted to enter the usual central opening of the watch dial has a shank 8 which extends through an opening in the portion 3 adjacent to itsextremity. The

shank 8 also extends through an opening in a pointer 9 which is held flatwise against the extreme end portion of the spring clamping arm 3 by a knurled nut or cap lOlwhich threadedly engagesthe shank 8. The pointer 9 is adapted to be swung about the axis of the shank 8 and therefore about the axis of the dial 6 when the thumb nut 10 has been loosened slightly to point to any one of the usual graduations on the front face of the dial, and the pointer 9 then may be secured in adjusted position with respect graduation by tightening the thumb nut 10.

The reduced portion 4* of the second spring clamping arm extends at the rear of the dial 6 and carries a clamping member 11 which issecured by a fastening element 12 to the reduced portion 4 of the spring clamping arm in position on the latter to abut the central portionof the dial so that the adjacent end of the pivot element 7 vis received in a cavity 13 in the adjacent face of the member 11.

The divergent portions of the spring clamping arms 3 and 4 are provided with alined slots 14 and 15 respectively which extend longitudinally of the clamping arms and through which the shank of a screw 16 extends, the head of the screw abutting the spring arm 3, and a knurled nut 17 being screwed on the shank ofthe screw against the spring clamping member 4. It will be manifest that the spring clamping arms will be forced toward each other when the nut 17 is tightened so that the central portion of the dial 6 will be held firmly between the pivot element 7 and the clamping member 11.

The spring clamping member 4 is provided adjacent to the side edges thereof, and at the juncture of the reduced portion 4:? and the remainder of the spring clamping member 4 with transversely alined stud projections or screws which serve as pivot elements for a pair ofswingable arms 18. Nuts 19 threadedly engage the outer ends of the pivot elements just referred to, and may be tightened to secure the arms 18 in ings in secondary swingable .arms 20,iinuts 21 being in threaded engagement With the pivot elements connectingthe arms 20 with the arms 18 and being adjustable to secure the arms 20 in adjusted angular relation to the arms 18. The. nuts 19 and 121 are..provided .Wltll head portions, each of whichhas a transverse opening; indicated .at"22 adapted to be engaged by a reduced; end portion 23. ot a turning. toolflornlieyfid, shown in Figure whereby then'uts 19:and 'EZLc-an ,be conveniently turned totighten. or loosenytoe same, asidesirjed.

' The arms 20 are provided-adjacent to their free ends with.transverse openings 25, each of which is adapted to receive theextending end portion of a stud projection 26 on, the rear face ofthe Watch dial. The ,openings 25 are intersected by lateral threaded bores in which the-shanks of set screws'27 are threaded for locking the arms .20 to the stud projections- 26.

When the arms 20 have been made vfast to the stud projections 26 and the clampingmembers 3 and 4. have been secured in such position in respect to-each other that the Watch dialis held firmly between; the elements 7 and 11, the operator can make the exactmeasurements on the xvatchto which the dial is to be transferred and can determine the exact space betweenthe feet on the dial betore it has been removed .t'rom the Watch.
